Abstract: Envelope of non-woven or other material filled with "Motte" substrate or various products, characterised in that it composed of a first mat of non-woven or other material, shaped in a general manner to a stainless steel tube, so as to match the outside of the tube, then the envelope thus shaped is thermo-welded under the pressure of an iron. The envelope of non-woven or other material thus shaped and thermo-welded is filled with substrate or with various products conveyed by an Archimedes screw under pressure, the envelope of non-woven or other material moves forward and comes in front of a cutting or lengthing station, from where we obtain an envelope of non-woven or other material filled with "Motte" substrate or other "container or wrapper" product. Using a second mat of non-woven or other material, the end is closed in the shape of a capsule which is also shaped and thermo-welded on the external diameter of the envelope of non-woven "Motte" or other material, but using a mechanical, electro-mechanical or other method. The envelope of non-woven material filled with "Motte" substrate or other products is separated from the second mat, from where we obtain a "Motte" enveloped with non-woven or other material, filled with substrate or other products and closed at one end which is the object of the invention.
Patent FR-2573481-A1 (FR)
Title: Engine with a crosshead mechanism with variable stroke and compression ratio
IPC: F02B75/24
Filed: 1984-11-22
Abstract: The orbital travel of the crosshead 23 may be modified so as to change the stroke of the pistons and the compression ratio of the engine. A crank element 25 has a crank pin 24 which carries and positions the crosshead 23. A sleeve 32 of the crank element 25 is supported by an adjusting shaft 29 with offset of centre lines. Control gears 41 to 43 normally drive the adjusting shaft 29 in synchronisation with the crankshaft 26, so as to keep a constant stroke and a constant compression ratio. The movement of certain control gears carried out by a control device gives rise to an advancement or retarding of the rotation of the adjusting shaft 29, so as to bring the crank element 25 into a new position, so that the orbital path of the crank pin 24 and of the crosshead 23 which are coaxial to the axis of the crankshaft 26 is modified. Orbits with low compression ratio and high compression ratio for the crosshead 23 may be chosen in order to best suit the load conditions of the engine. A crankshaft throw with variable length 27 couples the crosshead 23 to the crankshaft 26.
